Problem with TI-86 screen

  1. Sep 8, 2008 #1

    I don't know if this is the right place, but I figured there'd be people here who know a thing or two about the said calculator model. My TI-86 is and old one (ca. 5 years). I didn't use it in the summer, and when I took it out again, there were multiple dead lines on the LCD screen. Is this a common problem with a calculator as old as mine? Can I do anything about it?

    Thanks for your help.

    Try replacing the battery first. If the problem persists, there's nothing that you will be able to do about it -- at least not without some pretty serious electrical engineering experience.

    i'd go for chroot's solution. if that fails, try this:
    i have a TI-86 as well and sometimes it gives me strangely colored lines, but when u rub them a bit it goes away. same thing with defect PC monitor pixels.

    if even THAT fails, use the ANCIENT METHOD:

    HIT ON IT!

    - less than 5% chance on wooden and simple plastic objects
    - 5-25% chance on complex plastic objects (like beach chairs)
    - 25-50% chance on mechanisms (like sophisticated toy cars and bycicles)
    - 50% + CHANCE on ALL ELECTRONICS (except Microsoft. they fail anyway :p )
